Table 3:

Pearson’s correlations, 95% intervals, and p values between histomorphometric measures (porosity and pore size) and μCT-based results (porosity and BMD). Significance for all correlations were assessed using non-parametric bootstrap (with resampling by specimen) to adjust for within-specimen dependence.
